The first 3D printed object was created in 1984 by Charles W. Hull. From the cost of $20,000 for a printer to only $1,000 in the course from 2010 to 2013 alone. Now this technology no less than 2 years has been growing in popularity and the uses of it. As in my last blog, NASA has made a rocket injector (fuel injector) using 3D printing. As more attention is attracted to this technology, more of the bigger companies are buying printers and coming up with cheaper and easier ways to innovate. As it began growing in popularity, their uses were only for creating small objects such as cups or decorations. Since then, now their uses range far and wide, ranging from a mere simple printed name to a working bicycle to a working weapon. Caused by the uses and possibilities this provides, are many risks and many dangers. The reliability and efficiency it provides even NASA has uses for it. Instead of sending a space ship to give simple tools to the space station, a new one can be printed on the station. As NASA plans to send 3D printers in space for use, a Boston hospital recently 3D printed a toddler's brain before his actual hemispherectomy to insure success. Hemispherectomy is one of the rarest and most challenging surgery which half of the brain is removed or disabled. The versatility is said to boost economies and help smaller businesses.
